Hey @philosophizer, welcome to Steemit! We're glad to have you here :)
And yes, I always take time to plan my posts, edit them, and read over (or watch) them before posting. I ask myself if what I'm posting is something I would want to see (or read) on Steemit. As I mentioned in my video, I spend roughly 4-5 hours a day planning, shooting video, editing, commenting, etc. And it's really paying off because my content comes out better and I create some awesome dialogue with my followers.
Anyways, I appreciate your feedback. And wish you much success here on Steemit! :)
